  • Patent number: 9607097
    Abstract: Systems and methods for fault tolerant content delivery. A request is received from a user for customized content on the network, the request for customized content comprising an identifier for the content and identification information. The request is forwarded from the user for the customized content over the network. Generic content corresponding to the customized content is stored in a cache for future use. The generic content is sent to the user if no customized content is received in response to the forwarded request from the user.

  • Patent number: 9401711
    Abstract: A circuit of an output stage of a push-pull driver having dynamic biasing may include a stacked configuration of field effect transistors (PFETs) having a first PFET, a second PFET, and a third PFET, whereby the first PFET is connected to a first supply voltage, the third PFET is connected to an output of a switchable voltage bias generator circuit, and the second PFET is electrically connected between the first PFET and the third PFET. A transmission gate may be connected to a second supply voltage, whereby the transmission gate electrically connects the second supply voltage to an electrical connection between the first PFET and the second PFET based on a first operating state for preventing a voltage breakdown condition associated with the stacked configuration of PFETs. The third PFET is bias controlled via the switching of the output of the switchable voltage bias generator circuit.

  • Patent number: 9343112
    Abstract: Methods and systems to provide supplemental content to a user who is viewing video or other content. The user's device (through which he will access the video) then provides an identifier of that video to a server or other computing facility. Here, the video identifier is used to identify supplemental content that corresponds to the user's video. The supplemental content is then provided to the user device for the user's consumption. The supplemental content may be structured in such a way that pieces of the supplemental content are accessible at particular points in the video. The piece(s) of the supplemental content available at a particular point in the video will be related to one or more objects that are present at this point. This allows a user to access one or more pieces of supplemental content in a context-specific manner, at a point in the video where the piece(s) of supplemental content are relevant.

  • Publication number: 20150189373
    Abstract: Methods and systems to improve the efficiency of a content delivery system. A local distribution node is introduced to the network, between the content provider and the end user device (i.e., the leaf node). The local distribution node is responsible for servicing a localized subset of the leaf nodes that would otherwise be serviced by a conventional server of the content delivery system. Requests for content are received at the local distribution node from leaf nodes, and content is received at the local distribution node for transmission to the leaf node(s). Content may be cached at the local distribution node to allow faster service of subsequent requests for this content. Caching may also be used to make the channel surfing process more efficient. If demand is high, a leaf node may be promoted to serve as an additional local distribution node. Leaf nodes may also share content among themselves.

  • Publication number: 20150188756
    Abstract: Methods and systems to indicate events of interest to a user. IN an embodiment, an event processor queries each of a plurality of event data sources, then receives event data from one or more event data source. The event processor then identifies an event to be indicated to a user device based on the event data. The identified event to the user through a user device. The event processor may receive, via the user device, feedback regarding the identified event. This feedback may be used to train future event identification. The event processor may be implemented at a computing device that is remote from the user, such as a server. Alternatively, the event processor may be implemented internal to the user device.
